Plain answer
What this page is about
For POTS, the app matters less than whether you can keep using it on low-energy days and bring a clear history to the clinician who asks what changed.

Why it matters
What to look for in a POTS tracker
- Orthostatic vitals should stay connected to symptoms and daily context.
- Salt, water, medications, heat, illness, and flare notes should be easy to add.
- The app should help with appointment prep, not only daily tracking.

| Orthostatic vitals | May be separate or missing | Built into the tracking flow |
| Salt and water | May need workarounds | Tracked beside symptoms |
| Appointment prep | Often requires manual summary | Doctor-ready report workflow |
